Heat oven to 375 degrees F.
In mixing bowl, whisk together flour, sugar, baking powder and salt.
Add flour mixture to food processor with butter and pulse about 20 times until butter is incorporated. Alternatively, grate or cut butter into flour mixture until well incorporated.
In small mixing bowl, gently whisk together the cream and egg. Pour half of the mixture into the flour mixture and gently stir. Add the vanilla extract and remaining cream; continue to stir until just blended.
Add berries to the dough mixture and gently stir until the berries are evenly distributed. Doug should be shaggy, but still resemble dough. If too shaggy, add a little more flour up to 2 tablespoons.
With spoon, drop onto baking sheet, spaced about two inches apart.
Bake for 20 - 25 minutes, until tops are light, golden brown.
